That being said, there used to be quite a lot of prejudice against Catholics. Some were concerned that the primary allegience of a Catholic would be to the Pope - which concern was largely eliminated by the Kennedy presidency.
Actually, it is my understanding that initially Catholics were excluded from the right to bear arms. I read this just recently but can't remember where. Perhaps someone else is more familiar with this edict and if and when it was repealed. I'm quite certain that applied to blacks as well.
I digress. Sorry.
